- walls 2 and 31, and around the shells 8 to the outlet and duct 6, battles 4O directing the gases along the lower ends of the tubes and valves 41 controlling the passes between the walls 2 and shells 8. The ballies 35 prevent the escape of green gases distilled from fuel in the top of the chamber 24; and compels such gases to pass out through a hotter, lower zone so as to efliect more Complete combustion.

The grate 25, as illustrated in Figs. 3 and 4-, comprises wheels 25 fixed on the jour lltllfil'l shaft 26, rings 25 having a limited turning movementon the wheels, and the grate bars 25 having the journals 25' in the rings 25 and the slotted flanges 9:3 engaged by the studs 25 fixed to the wheels 2.5. These grate are adapted to occupy the position shown at the right of Figs. .l and 3 when rising; and that shown on the loft oi these figures when descending, so that in their descendina movement they a adapted for engaging; and. grincu ashes in. the bottom at the chamherfl-n, the opera tion turning the grate bars 2"." and the ashes falling; into the hopper 2% As illtstralcd in Fig. the foundation ll, the outer watls f3 and 2/ wh ch support the floor o. and the intermediate walls 5? with bcrs t and the flue. 6 c-mmnunicatiu The chambers t have 'tlnilrein the banks oi substantially ulzright, oppositely inclined :ubes 7 with-the shells or drums 8 connecting their lower ends and. connected by the conduit l, the tll m oil. the tubes being conmin'tetl with licvllr s 5,?" which are connmwted by lieatleis w' a steam collecting or drum l3) Headers i conn d with the headers 9", are connected by es 1' with the drum iii, the to being molested by the balllinn- 29. Headers il and 9 con hurled with headers 9", are connected respcctii'ely with a header by tubes 12 and nilh the .-.hell 1.3 by tubr- 12*. Tubes mulfilf' connect the header H i and 9" with the respective shells 19 and 1.9", which are roamerted by the respective corniluits 19 and lil with a conduit 15 communicating with ill shell til. Tubes 16, cm'crctl by battling 1b", are connected with the shell 13 and th shall Tubes 26', covered by battling ,see

35, connect the shell. 13 with a shell 21, the latter being connected by a conduit 19 with the conduit. 15, and tubes 20" connect the shell 21 with a shell 2i, V

A revolving grate journaled by theshaft :26, is disposed'betwecn the shells 19 and 2]., and a revolving grate bar 27 is disposed between the grate and the shell 21". Fuel is fed to the grate mechanism and the primary combustion chamber 24 from the inlet 2-7, through the chamber or passage 2%" formed by the tubes 18" and the grate 18' on the tubes 18. Air is admitted to the primary combustion chamber through the inlet 37, the chamber 36' and between the tubes '18; also between the tubes 18' and through the perforated grate 18 thereon, and through the grate mechanism comprising the parts 25 and 9".

The gaseous products of combustion flow from the chamber 24; between the tubes 20 to the secondary combustion chamber 38, thence in contact with headers 9' and dowmvardl; along the tubes 7 between the walls 2 and ballling 31, thence around the drmus 8 beneath the floor 34, thence upwardly along" the tubes 7 between the wall with the lmlliingextension 2 thereon and the batllc 31 into contact with headers 9', and thence through. the chamber 6", passage ii and flue 6, the green gases being directed downwardly thrl'mgh the hotter zones to crnnpleto their coi'nb'ustion by batlles 16" and angle oi more than i'orti l vc degrees with :1 horizontal plane.
